- the present invention accordingly provides a method for the control of the growth of weeds at a locus which comprises applying to the locus a compound of general formula I, or an agriculturally acceptable salt or acid addition salt thereof, or a herbicidal composition according to the invention.
- amounts of active ingredient ranging from 0.5 to 10 kg/ha give good results, it being understood that the choice of the amount of active ingredient to be used depends on the severity of the weed problem, the climatic conditions and the crop in question.
- the treatment is generally carried out as a pre-emergence treatment of the crops and adventitious plants or as a pre-sowing treatment of the crops, with incorporation into the soil, although in certain cases, depending on the compound used, good results can also be obtained by post-emergence treatment.
